Want to know a secret? Typical bleach levels are no match for surface mould. On a porous material, moulds take root and multiply rapidly, growing your microscopic problem into a room-sized one in no time.
It’s easy to ignore a little mustiness or some stubborn, dark marks by your bed, especially when you spend 21 years of your life in your bed. But overlook surface mould for just a little too long, and you’ll wind up spending a lot of time and money to get rid of it.
Before that furry smudge grows out of control, get rid of mould in your room with a special cleaning procedure. Then make sure it never comes back by using smart prevention measures.
Indoor Mould Symptoms
Even if you don’t have plants as part of your home’s decor, you could still have a plant problem. Mould gets into your home indoors in a number of ways, such as microscopic spores on timber if they have not been dried properly or a little patch of slime on a sink splashback tile or silicone.
However it’s introduced, you’ll want to get rid of it as quickly as possible. If you fail to maintain balanced building science, you might as well formally invite your mould to make itself at home in your home and stay forever.
Unlike the harmless moulds found outside, some of the types of moulds found indoors are harmful to occupants. But mould in your home can cause mustiness so thick you wouldn’t be able to breathe without using a mask. They also provide food for some types of bacteria you don’t want in your home. Plus, smelly indoor air is just uninviting, to say the least.
Mould’s most noticeable symptom is less fresh room air. Depending on the type of mould infesting your room, the surfaces in the room whether part of the home or part of the furnishings may be whitish, greyish, or even shadowy. Gross, right?
Another tell-tale sign is residue in any of those colours in corners, under stairs, on room walls, and around air con and floor vents. Mould loves to grow in nooks and crannies where you may not see it until it’s too late.
Mould found in water-damaged buildings comes in various types, each with its own characteristics, health impacts, and resistance to removal. Understanding the type of mould you’re dealing with helps determine the best way to handle it. Here’s a breakdown of some of the most common moulds you might find indoors in water-damaged environments.
Aspergillus is one of the most common indoor moulds, often appearing in green, white, or yellow. It typically grows on walls, insulation, and wooden surfaces in homes with high moisture levels. Long-term exposure can cause respiratory problems, especially for people with asthma or weakened immune systems. To tackle it, thorough cleaning and controlling moisture is key, but in severe cases, it’s best to call in a professional.
Cladosporium prefers cooler environments and is often found on wood, fabrics, and even HVAC systems. It tends to be black or green and spreads quickly. This mould can cause allergic reactions, skin rashes, and asthma. Cleaning affected areas with a mould-killing product and improving ventilation will help prevent future growth.
Stachybotrys, often called black mould, thrives in places with constant moisture, like behind walls or under carpets. This mould is known for being particularly toxic and dangerous, producing mycotoxins that can lead to severe health problems such as breathing difficulties, chronic fatigue, and cognitive issues. Immediate professional help is required to remove it safely.
Penicillium is another common mould in water-damaged homes. Its blue-green appearance makes it easy to spot, and it often grows on wallpaper, carpets, and insulation. Exposure can cause allergies, asthma, and sinus infections. Removing affected materials and thoroughly drying the area is essential to stop it from coming back.
If you notice a musty smell in a water-damaged area, it could be Chaetomium. This mould grows on drywall, carpets, and wallpaper, starting off white and darkening over time. Long-term exposure to Chaetomium can lead to neurological damage, particularly for those with compromised immune systems. The key to dealing with it is removing moisture, using antifungal agents, and fixing any sources of water damage.
Alternaria is frequently found in damp spots like showers, bathtubs, and under leaking sinks. It’s usually dark green or brown and has a velvety texture. Exposure can trigger allergic reactions, asthma attacks, and skin infections. Scrubbing the affected areas with a mould-killing solution and fixing leaks is essential to keep this mould at bay.
Ulocladium thrives in areas hit by extreme water damage, such as after flooding. It appears in dark colours, usually black or brown, and is commonly found in bathrooms, kitchens, and basements. This mould is known for causing severe allergic reactions and respiratory issues. To handle it, you’ll need to address the water source immediately and remove affected materials. In severe cases, professional help might be necessary.
Fusarium can grow even in cold conditions and is often found on water-damaged carpets, wallpaper, and fabrics. It’s typically pink, white, or red. Exposure can lead to skin infections, respiratory problems, and in some cases, life-threatening infections. Removing contaminated materials and ensuring the area is thoroughly cleaned and dried is essential for proper treatment.
Knowing which type of mould you’re dealing with is essential for effective removal. Different moulds pose different health risks and require specific approaches. Start by investigating the source of moisture, since mould only thrives in damp environments. Fix any leaks, improve ventilation, and reduce humidity to prevent future growth. Always wear protective clothing, gloves, and a mask when handling mould, and seek professional help for toxic or widespread mould. Preventing recurrence is key—make sure the area is thoroughly dried, and consider using a dehumidifier or improving insulation to keep moisture levels down. Spotting mould early and acting fast can help keep your home healthy and safe. Prevention is always better than cure!
